Segmentation results of our method and the method of Yang et al. (2019). The first column shows the input image, and the second and third columns present the segmentation results of our method. The fourth and fifth columns show the segmentation results from the method of Yang et al. (2019). The red boxes show that our method can effectively deal with complex-shaped MBPs, while the method of Yang et al. (2019) misses some detections and produces incomplete segmentation of complete block-shaped MBPs.
